Run python inside python and capture output

This is taken from http://techkr.blogspot.com/2007/02/python-how-to-get-output-from-ossystem.html:

How to execute python inside python and capture output:

A quick solution using popen :

import os
result=os.popen('command').read()
print result

where command is your command (expl. on windows: dir,ipconfig,...)

If you expect more than a line and want each word in a list:

import os,string
result=string.split(os.popen('dir/w').read())

I found this poster on a the Scientist Creative Quartely page at UBC, I thought it was funny ! That's a remix of the trainspotting poster.

Songbird - Ubuntu Jaunty

I had some error while trying to launch songbird on ubuntu jaunty 32 bit.

I found on a website that this package needs to be removed

sudo apt-get remove libvisual-0.4-plugins

libvisual is the plugin that displays some images while playing music in some music players like totem...

I removed it from the system and I can now launch Songbird.

Here is the error I was getting when running songbird:

./songbird
